condenser

The word 'condenser' is built from the verb 'condense,' which entered English in the late 16th century from the Latin condensare, meaning "to make thick, to press close together." This Latin verb itself is a compound of the intensive prefix con- and the adjective densus (thick). The literal sense of "making particles come thickly together" provides the logical bridge to its modern meanings. A condenser, therefore, is an agent or device that causes a substance (like vapor) to become denser or more compact, either by cooling it into a liquid or by focusing energy (like light) into a concentrated area. The application to electrical charge storage (capacitor) extends this core idea of concentration and accumulation.

Structure: con (together) + dens (thick) + er (agent suffix) - con-: A prefix from Latin, meaning "together, with, thoroughly." It functions as an intensifier in this word. - dens: A root from Latin densus, meaning "thick, dense." It forms the core semantic element. - -er: A suffix from Old English -ere (agent noun suffix), used here to form a noun denoting an agent or device that performs an action.
